[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1:

[0023] Please see Figure 1-3This utility model provides a technical solution: a protection device for settlement observation measuring points, comprising: a base plate 1, a protective box 2 fixedly connected to the upper end of the base plate 1, a box cover 3 rotatably connected to the rear side of the upper end of the protective box 2, an observation through hole 4 opened at the lower end of the interior of the protective box 2, a shell 5 fixedly connected to both sides of the upper end of the base plate 1, a positioning rod 6 and a positioning component 7 provided at the front and rear ends of the shell 5, the positioning component 7 being located on the shell 5, and the positioning component 7 being used to drive the positioning rod 6 to move up and down.

[0024] In this implementation plan, the base plate 1 and the protective box 2 are first placed on the observation point through the observation through hole 4. Then, the rotating wheel 72 is rotated. The rotating wheel 72 drives the threaded rod 71 to start rotating through the bearing seat 11. The rotation of the threaded rod 71 drives the threaded block 73 to move downward. The threaded block 73 drives the fixed plate 74 to move downward.
